A Notice of Violation or NOV is one step in EPA’s investigation and enforcement of violations of EPA statutes and regulations. A NOV notifies the recipient that EPA believes the recipient committed one or more violations and provides instructions for coming into compliance.
NOVs typically offer an opportunity for the recipient to discuss the their actions, including efforts to achieve compliance. NOVs are not a final EPA determination that a violation has occurred. EPA considers all appropriate information to determine the final enforcement response.
For an example of how NOVs are used, please see Civil Enforcement of Renewable Fuels Standard.
